Now the amp has a loud pop when turning on and VERY loud when turning off Since the resolder R20,R21,REG1 and REG 2 are all still very hot Previously R20,R21 and REG1 were getting VERY hot I found REG 2 point 'I' to only have a circuit on one side and not passing through to the other, I resoldered this ![]() I found REG 2 point 'com' to have had its trace completely broken, I managed to resolder it I had to put silastic under the REG's and resistors because the trace had lifted so no ensure no more movement * friend had tried to resolder some of the points.whether it was him or from the previous repair some were in very bad shape, traces lifting or broken *previous preamp tube had no glow to it, replaced I found a schematic here, it does not appear to be 100% accurate (I will explain why soon ) A friend of mine has a marshall valvestate vs265 amp that has had intermittent problemsīasically after a certain amount of time being on, a loud hum would come in and out through the amp, he said the previous owner had to get it repaired (mentioned resoldering stuff)
